In that case, you need to implement the delegate method "tableView(_:willDisplayCell:for:row:)”, which is called once for each cell that’s redrawn. In your method, you need to verify that the cell is of the type you expect (a NSTextFieldCell, I’m guessing), cast it to the correct type, and then set its backgroundColor property. Note that NSCell does not itself have such a property, it’s only implemented by specific subclasses. Alternatively, it is possible to prepare one cell per color at initialization, then supply the correctly colored cell at each row/column. This is slightly more efficient, because it doesn’t involve re-configuring the cell each time it’s used, but it’s a bit more code (also in the delegate). _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
